Transition metal dichalcogenides (TMDCs) are of increasing interest as promising contenders for a wide range of optoelectronic and electrochemical applications due to their strong light-matter interactions, tunable optical bandgaps and flexible two-dimensional (2D) structure [1]}, [2]}. Molybdenum diselenide (MoSe\(_2\) ) is one of the most promising TMDC candidates for photoelectrochemical energy conversion due to its photocatalytic properties and the electrical conductivity of Se [3]}, [1]}. MoSe\(_2\)  monolayers have a hexagonal crystal structure that consists of top and bottom Se layers sandwiching a Mo layer [5]}. Stacked MoSe\(_2\)  layers are weakly coupled via van der Waals coupling[6]} and have an interlayer spacing in bulk of 0.65 nm[7]}, [8]}, [9]}, [10]}, [11]}.
